Salty solutions will create a specific atmosphere inside of the bag because of the modified vapor pressure. Just using distilled water, for example, would give you exactly 100% RH, and a saturated lithium chloride solution would give you about 11% RH. Keep in mind that this is true only at room temperature (20 °C), the whole process is temperature-dependent. Table salt (sodium chloride) tends to be very stable in that regard (less than 1 % change between 0 °C and 30 °C).
